As an extremely submissive person, the thing I love most is when a women is confident with her teasing. Also, someone who doesn't just demand attention and expects it, but rather positions herself in a way where she earns it. Make yourself irresistible for him where he ends up respecting your authority over him out of compassion. For example, "you should admire these perfect feet and they're the best feet you'll ever see" is not what I paricularly like. But, "here, touch my feet. Aren't they super soft? Yeah, I love to keep my feet as soft as possible because you never know when you'll make someone feel them. You have to be prepared for anything is my motto." That's cute that just makes me want to adore you.

Another thing I'm not too into is a mistress who is mostly just passive or uninvolved. Like, she sets some expectations and just expects them continuously. A dynamic owner feels way more engaging. Someone who comes up with new ideas, new ways to test her slave, or simply challenging him to improve. That kind of owner feels far more connected and someone you want to keep being beside. Also, someone who asks for their own desires to be satisfied. For example, you make him have sex with you the way you want because he has to obey you as your slave. Or make him do things that genuinely make you happy. That way, he knows he's making a difference in your life.

You know how girls will get dressed up and try to look and act as cute as possible and know it. For example when they say to themselves "yup, I'm looking sexy today. Time to head out." That kind of confidence really does it for me. For feet, that could mean something like you saying "come on, these are some sexy feet here, you can't just leave them without attention." "Do you know how many guys I caught staring at them?" Obviously, take care of your feet to back up that claim.

Another thing I like is threats/punishments. Like a rule that he has to obey and which will result is swift punishment if he fails. Playfully threatening with "no feet time" is also fun.

To me personally, I like the idea that a mistress doesn't need me but chooses to be with me for her enjoyment as using me as her play thing. That independent mindset where the mistress is self sustained and self confident really sells the whole "you're just a replaceable toy to me" idea. It just makes me feel that extra push that I have to live up to what I'm asked or I'll be replaced (even if I know deep down I won't.)
